Hormonal acne often stems from insulin resistance, which disrupts hormone balance and triggers excess oil production, leading to persistent acne. Metformin, a medication commonly used for managing insulin resistance, has shown promising results in reducing acne severity by addressing the root cause rather than just the symptoms. Studies reveal that over 80% of acne patients exhibit insulin resistance, and treatments targeting this issue can significantly improve skin health.
Key Takeaways:
- Insulin Resistance and Acne: High insulin levels increase androgen production and reduce SHBG, leading to excess oil and clogged pores.
- Metformin's Role: Improves insulin sensitivity, reduces androgen levels, and lowers acne severity by up to 86% in clinical studies.
- PCOS Connection: Women with PCOS often experience acne due to insulin resistance, making metformin an effective solution for both skin and metabolic health.
- Treatment Insights: Typical starting dose is 500 mg twice daily, with gradual increases. Side effects like nausea can be managed with food or extended-release formulations.
Metformin offers a science-backed approach to hormonal acne, addressing its underlying metabolic dysfunction while promoting clearer skin and better overall health.

The Science Behind Insulin Resistance and Hormonal Acne
Understanding how insulin resistance impacts the body sheds light on its connection to acne and why addressing it can help improve skin health.
How Insulin Affects Hormone Balance
When insulin resistance takes hold, it disrupts the body’s hormone regulation in critical ways. Both insulin resistance and acne are linked through specific cell signaling pathways, particularly the mTORC1 and IGF-1 pathways. These pathways are essential for normal cell signaling, but when altered, they can disturb hormonal balance and contribute to acne development.
At the cellular level, elevated insulin levels activate IGF-1 receptors, which trigger abnormal skin cell growth that clogs pores. Another key player, the mTORC1 pathway, becomes hyperactive in conditions like insulin resistance, obesity, and type 2 diabetes. This pathway has been found to be overactive in individuals with acne.
Insulin also influences the PI3-K/Akt pathway, increasing SREBP-1 expression. This leads to overactive sebaceous glands, which produce excess oil - a major factor in acne formation.
Dr. Jacqueline Zuponcic, DO, explains how hormones amplify these effects:
"Testosterone and DHEA tell your skin's sebaceous glands to produce more oil. These hormones can also slow down your skin's turnover rate, making the oil more likely to clog your pores. Together, these two factors lead to acne."
Acne reflects a systemic issue, as highlighted in one study:
"Acne should be obviously considered to be a systemic disease, which requires a complex and personalised therapy."
These findings explain why topical treatments often fall short, as they don’t address the deeper hormonal and systemic causes.
Insulin Resistance in Women with PCOS
For women with polycystic ovary syndrome (PCOS), insulin resistance plays a significant role in both reproductive and skin health issues. Insulin resistance is a hallmark of PCOS, affecting 35% to 80% of women with the condition. Importantly, this resistance occurs regardless of body mass index (BMI) or body fat distribution.
PCOS impacts 5%–10% of women of reproductive age. Without proper management, the body compensates for insulin resistance by producing more insulin, which further disrupts hormonal balance. This cycle not only impairs ovarian function but also contributes to persistent acne.
The connection between insulin resistance and acne becomes clear when examining how excess insulin stimulates androgen production in the ovaries and adrenal glands. Elevated androgen levels create a hormonal environment that promotes acne.
The broader health implications of PCOS are significant. Over half of women with PCOS develop type 2 diabetes by age 40. Additionally, the National Center for Chronic Disease Prevention and Health Promotion notes:
"PCOS is also linked to depression and anxiety, though the connection is not fully understood."
However, there is hope. Dr. Jacqueline Zuponcic emphasizes the availability of effective treatments:
"Safe, effective therapies are available and you deserve a chance to look and feel your best."
Lifestyle changes, such as maintaining a healthy weight and incorporating regular physical activity, can reduce the risk of type 2 diabetes for women with PCOS. Yet, due to the complexity of the condition, medical treatments are often necessary to address both insulin resistance and its effects on the skin.
These insights pave the way for exploring targeted solutions like metformin, which will be discussed in the next section.
Metformin: Treating Hormonal Acne at the Source
Metformin tackles hormonal acne by addressing one of its primary causes: insulin resistance. By improving how the body handles insulin, it helps break the cycle of hormonal imbalances that trigger excess oil production and clogged pores.
How Metformin Improves Insulin Function
Metformin works on multiple levels to restore insulin function throughout the body. It enhances insulin sensitivity, lowers insulin levels, and improves how fat tissue (adipose) functions. On a cellular scale, it reduces glucose production in the liver, boosts glucose uptake in peripheral tissues, increases insulin receptor activity, promotes glycogen synthesis, and enhances glucose transport through GLUT4 proteins.
A key part of metformin’s action involves activating AMPK (adenosine 5′-monophosphate-activated protein kinase), an energy sensor in cells that plays a major role in metabolism. This activation improves insulin sensitivity and can lower ovarian androgen production by 20% to 25%, directly targeting the hormonal imbalances that contribute to acne.
Interestingly, metformin isn’t just effective for individuals with higher BMIs. While it’s often prescribed for women with PCOS and elevated BMI, research shows that women with lower BMIs may see even greater benefits. For example, a study involving 35 women with PCOS found that after six months of treatment with either metformin or rosiglitazone, GLUT4 mRNA expression in fat tissue significantly increased. This was accompanied by a marked improvement in HOMA-IR scores, a measure of insulin resistance. These cellular-level changes translate into real-world improvements in hormonal acne.
Clinical Studies on Metformin for Acne Treatment
Clinical research supports metformin’s effectiveness in reducing acne severity. Studies consistently show significant improvements, with reductions in acne severity scores ranging from 40% to over 80%.
A meta-analysis of 51 studies involving 2,405 patients with PCOS highlighted metformin’s impact when used alongside other treatments. It showed a notable improvement in acne scores (SMD −0.256; 95% CI −0.439 to −0.074) and a further significant reduction in acne severity (SMD −0.712; 95% CI −0.949 to −0.476). Additionally, it decreased the incidence of acne (OR 0.362; 95% CI 0.271–0.485).
In a study conducted at SMS Hospital in Jaipur, India, 40 women with PCOS and acne were treated with 500 mg of metformin three times daily for eight weeks. The results were striking: acne severity, measured by the Definition Severity Index (DSI), dropped from 80.81 ± 46.29 at the start to 9.70 ± 8.5 by the end of the study - a remarkable 86.01% improvement (p < 0.001).
Moreover, metformin’s benefits extend beyond patients with PCOS or other hormonal disorders. Research indicates that it can also help individuals without underlying endocrinopathies. By improving insulin sensitivity and balancing hormone levels, metformin addresses a key driver of hormonal acne, making it a promising option for long-term management.

Metformin Treatment Details for Hormonal Acne
Metformin's ability to improve insulin sensitivity makes it a promising option for managing hormonal acne. Here's a closer look at how metformin is used and what to expect during treatment.
Metformin Dosages and Treatment Plans
For adults, the typical starting dose is 500 mg taken twice daily, with weekly increases of 500 mg until reaching a maximum of 2,550 mg per day. For younger individuals aged 10–16, the starting dose is the same, but the maximum dosage is capped at 2,000 mg per day.
Clinical studies highlight effective dosing strategies. Research by Fabbrocini et al. and Albalat et al. both utilized 500 mg twice daily, showing significant improvements in acne severity. For instance, Global Acne Grading System (GAGS) scores dropped from 25.1 to 14.1 and 25.2 to 13.6, respectively, with minimal side effects reported.
Clinicians often assess progress at weeks 3, 6, and 8. One study noted a 47.22% reduction in acne severity after just three weeks, which increased to 86.01% by the eighth week.
Understanding the safety profile is the next step to ensure effective and tolerable treatment.
Side Effects and Safety Considerations
Managing side effects is key to maintaining the benefits of metformin. Gastrointestinal issues are the most common, affecting up to 30% of patients. Symptoms like nausea, diarrhea, bloating, gas, and stomach pain can often be minimized by taking metformin with food and gradually increasing the dose. Extended-release formulations are another option, as they tend to cause fewer digestive issues.
Here are some tips for managing common side effects:
- Nausea and stomach discomfort: Take metformin with meals and eat smaller, more frequent portions.
- Diarrhea: Stay hydrated and consider switching to an extended-release version.
- Metallic taste: Chewing sugar-free gum may help alleviate this symptom.
Serious side effects are rare but worth noting. Lactic acidosis, though extremely uncommon, is a potentially life-threatening condition. Diana Isaacs, PharmD, explains:
"Lactic acidosis is a very rare side effect. It's more likely to occur if there are super high levels of metformin in the bloodstream and someone has reduced kidney function where it's not being cleared out."
Long-term use may lead to vitamin B12 deficiency, so regular monitoring and supplementation might be necessary. Hypoglycemia is another potential concern, especially when metformin is combined with other medications or during irregular eating patterns. To prevent low blood sugar episodes, it's important to maintain regular meals and carry fast-acting carbohydrates.
In clinical studies, side effects have generally been mild. For example, in the Albalat study, only six out of 50 participants experienced mild gastrointestinal discomfort, and three reported mild hypoglycemia episodes. Meanwhile, the Kamboj study, which used 1,000 mg daily for three months, reported no side effects.

FAQs
How does metformin help improve hormonal acne caused by insulin resistance?
Metformin can play a role in managing hormonal acne by tackling insulin resistance, a key contributor to acne. It works by improving the body’s response to insulin, which helps lower insulin and IGF-1 levels. This reduction leads to decreased androgen production - hormones that often cause excess oil and clogged pores.
By addressing this underlying issue, metformin not only aids in achieving clearer skin but also helps maintain better hormonal balance. If hormonal acne is a concern and insulin resistance might be a factor, discussing metformin with a healthcare provider could be a worthwhile step.
What side effects can metformin cause, and how can they be managed during hormonal acne treatment?
Metformin is often prescribed to address hormonal acne associated with insulin resistance. While it's generally well-tolerated, some mild side effects like nausea, diarrhea, stomach discomfort, or loss of appetite may pop up, especially at the start of treatment. The good news? These symptoms usually ease over time. To reduce the chance of discomfort, try taking metformin with meals, start with a low dose, and follow your healthcare provider's guidance to gradually increase it.
On rare occasions, more serious issues like lactic acidosis can develop, particularly in those with kidney problems. If you notice unusual symptoms such as extreme fatigue, trouble breathing, or muscle pain, it's crucial to get medical help right away. To stay on track with your treatment, remember to drink plenty of water, eat small and frequent meals, and consult your healthcare provider if any symptoms persist. This approach can help make your experience with metformin as smooth and effective as possible.
Is metformin effective for treating hormonal acne in people without PCOS or obesity?
Metformin might help with hormonal acne, even for those who don't have PCOS or obesity. Research indicates that the drug can decrease insulin resistance and lower androgen levels - two major factors behind hormonal acne. In fact, studies have shown noticeable improvements in acne severity among women with a normal BMI and no PCOS diagnosis.
This points to metformin's potential use beyond its standard applications, offering a possible solution for managing hormonal acne in a wider group of people. However, it's essential to consult a healthcare provider to see if metformin is a suitable option for you.
